'VENTl'LATlhlG-rWHEEL.

SPECIFICATION forming part of Letters Patent No. 497,413, dated May 16,1893.

Application filed July 13, 1892. $erial No. 439,877. (No model.)

To all whom it may concern.-

Be it known that I, MARTIN Rosn RUBLE, a

citizen of the United States, residing at Newark, county of Essex, andState of New Jersey, have invented certain new and useful Improvementsin Ventilator-Wheels; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

The object of this inventionis to provide an apparatus for ventilatingrooms, 850., simple and durable in construction, neat in appearance andeasily operated.

The invention consists in the improved ventilator, its connections, andthe arrangement and combination of the various parts thereof,substantially as will be hereinafter more fully described and finallyembodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the two views;Figure 1. is a side elevation of my improved ventilator and Fig. 2. asectional view on line 00 Fig. 1.

In said drawings a represents a hollow tube, provided at its upper endwith a series of rectangular flanges c, and air inlets 1), arrangedalternately with each other. The

lower end of said tubeis provided with a series of elongated slots d,and also with a threaded pin e, the latter being adapted to receive aninternally threaded knob f, serving as bearing for the hollowball is. Tothe upwardly extending flange m of said ball, is secured a grooved Wheelor pulley i,and to the outer peripherytwo or more radially extendingtubes h provided at their outer ends with elbows n. The pipe 9 connectsthe ventilator with a blower; or it can be cut off (disconnected), andserves then as an additional air inlet,) if said ventilator is operatedby belt or spring motor power) as will be hereinafter more fullyexplained.

There are two modes of operating said ventilator. When the pipe g isconnected with a blower, the air from said blower is forced through saidpipe into the hollow tube a, and through slots 61 into the ball 7r, fromwhere it enters the radial tubes 72, and, based on the principle of thewell known turbine wheels, causes said ball to rotate; when the tubesare passing through or cutting the atmosphere, a certain vacuum orsuction is produced, at their outlets, said suction releasing the blowerof a certain pressure or strain, as will be manifest. As the inflowingcurrent of air at the outlet (0) of pipe 9 produces a suction,additional airis siphoned in through openings 1) of tube a.

In case no steady air current can be obtained, for operating saidventilator, the pipe g is left Open (disconnected) and the ball 10 maythen be revolved by means of the pulley i, or in any desired manner. Therevolving tubes 71. will, when traveling through the air,

produce at their outlets a vacuum, thus sucking the air through openings1), and siphoning the air through pipe 9 as will be manifest.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a ventilator, the combination with a hollow ball, of a series ofradially extending tubes, arranged on said ball and provided at theirouter ends with elbows, a tube arranged in, and extending a certaindistance above said ball, said tube being provided at its lower end witha series of elongated slots, and at its upper end with a series of airinlets, and a pulley secured to and adapted to operate said ball, allsaid parts substantially as described and for the purposes set forth.

2. In a ventilator the combination of the tube 0., having at its upperend a series of air inletsb and atits lower end a series of elongatedslots d, with the ball is incasing the slotted end of said tube a andcarrying the curved radially extending outlet tubes h and with the pipeg leading from a blower or other source of air supply to and within theupper end of said tube a, said pipe 9 being of smaller diameter thantube a, and adapted when the air passes from the outlet end of said pipeg into said "tube a to create a suction in said tube, all arrangedsubstantially as and for the purposes set forth.

3. In a ventilator the combination with a tube, provided at its upperend with rectangular flanges and openings arranged alternately to eachother and at its lower end with a series of elongated slots, of athreaded pin secured to the lower end of said tube, an internallythreaded knob, secured thereto, a hollow ball adapted to be revolved onsaid tube and supported by said knob, two or more radially extendingtubes arranged at the outer periphery of said ball, and provided attheir outer ends with elbows, and a pipe arranged in said hollow tubeand adapted to conduct the air from a blower into said ball, all saidparts substantially as described and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this28th day of June, 1892.
